Given the facts stated, the most obvious explanation is that there's
something in your code that's dependent on a 32-bit environment ---
trying to store a pointer in an integer, say. Can't debug it for
you though. I'd suggest recompiling with full warnings (gcc -Wall
at least) and paying close attention to anything the compiler warns
about.
